The newborn's immune system is suddenly confronted with microorganisms, food and numerous environmental influences at birth. How do the baby's immune cells prepare for this moment during pregnancy and birth? How do external influences shape the immune system immediately after birth? And what influence does an event like a premature birth have?

Researchers successfully rejuvenate the immune system in animal models

It is well known that stem cells age. Even the human immune system loses its power with age. Since all immune cells are derived from blood-forming stem cells, it is quite natural to associate the weakening of the immune system (immune senescence) with the ageing of blood-forming stem cells. Stem cell researchers and immunologists from the University of Ulm have now demonstrated the important role that blood-forming cells play in the ageing of the…

A rapid pyrogen test: the human immune system as model

Every year, around 11 million people die of sepsis (blood poisoning) caused by microorganisms or microbial residues, known as pyrogens, entering the bloodstream. The smallest amounts can trigger fever. Researchers from the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB in Stuttgart have developed a pyrogen test that does not require a laboratory and is not tested on animals. It is expected to be placed on the market soon.

Targeting the protective shield of cancers

Cancer cells have different mechanisms to help them escape destruction by the immune system. Solid tumours, for example, are often surrounded by a protective layer of lactate, which has a strong immunosuppressive effect. WMT AG from Heidelberg is developing small drug molecules that reduce lactate production and thus make cancer cells vulnerable to immune system attacks.

Boosting the immune system can improve cancer prevention and treatment

The activation of the body’s immune system to fight cancer is not only a promising therapeutic concept, but is already used in medical practice. The first immunotherapies have been approved and many more are either in the experimental stages or already undergoing clinical testing. Vaccines to prevent certain types of cancer are already being used successfully around the world.

Can the weakened immune systems of older individuals be rejuvenated? Researchers from the DKFZ, HI-STEM*, and the Broad Institute have demonstrated that this is possible with an innovative approach. In a study, the team showed that mRNA technology can be used to transform the liver in mice into a temporary source of important immune regulatory factors that are naturally lost during aging.

"Innate cell engager" fighting against cancer

In the fight against tumour cells, d Affimed GmbH from Heidelberg relies entirely on the weapons of the innate immune system. Affimed has developed special innate cell engagers, which are bispecific antibodies that recognise tumour cells and bring them together with natural killer cells and macrophages of the innate immune system, which then kill the tumour cells. Clinical trials using the AFM13 molecule are ongoing.

New trends in the field of immunology

B- and T- lymphocytes along with macrophages have long been regarded as the most important cells of the human immune system and have been a major focus of research. This has now changed and it is now the dendritic cells that are regarded as the major components of the adaptive immune system. Research into innate immune defence mechanisms has become more important due to the discovery of the role of Toll-like receptors as first-line of defence.

Inhibition of a protein complex in cells of the immune system prevents rejection of transplanted organs – this has been shown in a study by immunologists from the University of Konstanz, the Biotechnology Institute Thurgau (BITg) and Chongqing Cancer University Hospital.

Nanobodies for determining neutralising antibodies after corona infection

After contact with a pathogen, ideally our immune system generates neutralising antibodies to prevent a future infection. With NeutrobodyPlex, scientists from Reutlingen and Tübingen have developed a highly specific test procedure based on single-domain antibodies (nanobodies) that can be used to easily and reliably determine the quality of the immune response against the novel coronavirus.

New treatment methods: DNA origami-based nanodevices precisely control immune response - 24/04/2025

Bottom-up synthetic immunology for novel therapeutic approaches

Modern therapies for combating cancer and infectious diseases increasingly leverage the body’s own immune system. Several research groups at Heidelberg University are using innovative bottom-up approaches in synthetic immunology to develop new treatment methods that can control the immune response more precisely than previously possible.

Researchers from Freiburg and Harvard publish the three-dimensional structure of the B cell antigen receptor, shedding new light on its composition.

Bacteria of the species Pseudomonas aeruginosa are antibiotic-resistant hospital germs that can enter blood, lungs and other tissues through wounds and cause life-threatening infections. In a joint project, researchers from the Universities of Freiburg and Strasbourg in France have discovered a mechanism that likely contributes to the severity of P. aeruginosa infections.

EMUNO Therapeutics: the innate immune system as a new approach to cancer treatment - 29/07/2026

Activation of macrophages: a key factor in the fight against colorectal cancer

The mobilisation of the body’s own immune system through immune checkpoint inhibitors has revolutionised cancer therapy. However, the majority of solid tumours are able to evade immune surveillance. These so-called 'cold' tumours contain too few immune cells to respond effectively to current immunotherapies. This is where the Freiburg-based biotech start-up EMUNO Therapeutics GmbH comes in.

Tumor vaccines can help the body fight cancer. Mutations in the tumor genome often lead to protein changes that are typical of cancer. A vaccine can alert the patients' immune system to these mutated proteins. For the first time, physicians and cancer researchers from Heidelberg and Mannheim have now carried out a clinical trial to test a mutation-specific vaccine against malignant brain tumors.

Medical Center – University of Freiburg demonstrates a fundamental therapeutic approach for hereditary immune system defects in a mouse model. The safety profile of genome editing varies significantly depending on the method and cell type.

The development of immunotherapies against blood cancer could be more successful if T cells are activated moderately rather than excessively. Scientists from the German Cancer Research Center have now been able to show this in mice: If the researchers blocked a cytokine that slows down the immune system, the T cells became exhausted and failed in the fight against leukemia.

Intestinal peptide heals lung - 14/10/2020

Inhalation of intestinal hormone VIP helps against immunotherapy-induced pneumonia

If cancer patients develop pneumonitis, an inflammation of the lungs resulting from immunotherapy, their symptoms and restrictions in lung function can often only be alleviated with cortisone. Researchers led by Prof. Dr. Joachim Müller-Quernheim and Dr. Björn Frye from the Freiburg University Medical Centre have been able to cure a patient's pneumonitis by inhalation of a long-known neuropeptide.

An environmental bacterium could protect against the effects of stress right through to the next generation. Evidence of this emerged in a study using a mouse model carried out by researchers from Ulm and Frankfurt, the results of which were published in the journal `Molecular Psychiatry´. According to the study, the offspring of treated mothers were better protected against the effects of stress in adulthood than control animals.

Researchers at the Faculty of Medicine of the University of Freiburg discover key factor in the development of immune cells. New approaches for the treatment of ALPS.

In people with severely compromised immune systems, the JC polyomavirus can trigger a currently untreatable, usually fatal brain disease. Now, an international research team looking at the viral capsid has identified binding sites for neutralizing antibodies; these sites could be used to halt infection with JC polyomaviruses.

A cutting-edge chemical process is the first to make it possible to quickly and easily produce modified peptides with boronic acids.
